West Ham have confirmed defender Joey O’Brien will leave the club after five years when his contract expires at the end of June.

The Irons issued their retained list on Tuesday afternoon, which also showed Cameroon midfielder Alex Song would return to his parent club Barcelona following the end of his season-long loan spell while winger Victor Moses goes back to Chelsea and Nigeria forward Emmanuel Emenike to Fenerbahce.

O’Brien, 30, joined West Ham on a free transfer from Bolton in June 2011, helping the east London club win promotion back to the Premier League via the 2012 Championship play-off final at Wembley.

However, last season the Republic of Ireland full-back made just seven first-team appearances, five of those coming in the Europa League qualifiers and two in the FA Cup, taking his total tally to 105 with three goals.

West Ham also revealed 21-year-old striker Elliot Lee, who had a loan spell at Colchester last season, was one of several youngsters not to be offered new terms and set to leave the club as manager Slaven Bilic prepares his squad for life at the Olympic Stadium.

Co-chairman David Sullivan, however, confirmed earlier this week five bids are in for new players as the club aims for signings with ”good value” in a ”potty” market, having been apparently priced out of any interest in Leicester striker Jamie Vardy.
